Answer :
The theoretical thickness of the piece of paper is not achievable in reality.
What is the geometry of a piece of paper?
The geometry of a piece of paper is a two-dimensional flat shape that can be described as a rectangle or square.
In geometry, a rectangle is a quadrilateral with four right angles (90-degree angles) and opposite sides that are equal in length.
A square is a special case of a rectangle, where all four sides are equal in length.
We have,
It's important to note that it is not possible to fold a piece of paper in half more than about 7-8 times due to the physical limitations of the paper's size and thickness.
However, we can still calculate the theoretical thickness of a piece of copy paper that has been folded 12 times.
Part 1:
When a piece of paper is folded in half once, the thickness doubles, so the thickness after one fold is:
0.1 mm x 2 = 0.2 mm
After the second fold, the thickness doubles again:
0.2 mm x 2 = 0.4 mm
We can see that with each fold, the thickness doubles.
So after 7 folds, the thickness would be:
0.1 mm x [tex]2^7[/tex] = 12.8 mm
Converting to centimeters, we get:
12.8 mm = 1.28 cm
Part 2:
Using the same doubling logic, we can find the theoretical thickness of a piece of paper folded 12 times:
0.1 mm x [tex]2^{12}[/tex] = 40.96 mm
Converting to centimeters, we get:
40.96 mm = 4.096 cm
However, as mentioned earlier, it is not possible to fold a piece of paper in half more than about 7-8 times due to physical limitations.
So this theoretical thickness is not achievable in reality.
Thus,
The theoretical thickness of the piece of paper is not achievable in reality.

Final answer:
When folded in half 12 times, a piece of copy paper would be approximately 20.48 cm thick.
Explanation:
Part 1: When a piece of copy paper is folded in half 7 times, the thickness doubles each time, resulting in a thickness of [tex]0.1 mm x 2^7 = 1.28 mm (or 1.28 cm).[/tex]
Part 2: If the same paper is folded 12 times, the thickness would be [tex]0.1 mm x 2^12 = 204.8 mm (or 20.48 cm)[/tex].
